Answer:
1. 18
2. 6
3. ?
4. 3
5. 4
6. 1
7. 5
Step-by-step explanation:
1. 6 x 3 = 18
2. 2 + 4 = 6
3. ( I cant read the problem)
4. 6 - 3 = 3
5. 2 x 2 = 4

7. 6 - 1 = 5
8. 6 + 2 = 8
Answer:
The 72 feet is measured on the slope, not out from the pole horizontally. I get
top of pole is at
40 + 72 sin17°
downhill point is
72 cos 17°
from point beneath the pole
cable^2 = (40+72 sin17°)^2 + (72 cos 17°)^2
